I wonder if using JSON as a data bridge works well in practice. If it does, I imagine that a polyglot jupyter notebook type must be on the horizon.

Part of the reason we built Beaker was that the IPython devs explicitly stated they didn't believe in multiple languages within one notebook. It's possible that this opinion has changed with the Jupyter migration, but I haven't heard anything to that effect.

Why did they object to multiple languages within a notebook? What problem did they think it would create?
